KARO TX25: Fix NAND Flash R/W cycle times

The NAND Flash of the KARO TX25 board is a Samsung K9F1G08U0B with 25-ns R/W
cycle times. However, the NFC clock for this board was set to 66.5 MHz, so using
the NFC driver in symmetric mode (i.e. 1 NFC clock cycle = 1 NF R/W cycle)
resulted in NF R/W cycle times of 15 ns, hence corrupted NF accesses.

This patch fixes this issue by setting the NFC clock to the highest frequency
complying to the 25-ns NF R/W cycle times specification, i.e. 33.25 MHz.
